# Initial D (video game series)

The Initial D (頭文字（イニシャル）D) video game series, known in Japan as Initial D Arcade Stage, is an arcade racing game series developed by Sega, based on the anime and manga series Initial D. In the United States and Europe, the game series is simply known as Initial D.

## Premise

In the Initial D video game franchise, players race against different opponents through various mountain passes featured in the manga. Vehicles that are featured in the game are mostly Japanese cars, such as the Nissan Skyline GT-R, Mazda RX-7, Subaru Impreza, Honda Civic, as well as the Toyota AE86. Using the optional magnetic card system (arcade instalments from Arcade Stage Zero and later utilize Amusement IC, Banapassport or Aime cards rather than dedicated magnetic cards), players can save a customized car as well as their progress for future sessions; otherwise, their game progress is deleted. Players can continue growth with their cards on another Initial D cabinet of the same version. However, the card must be renewed every 50 plays.
Resuming from another version is subject to the following conditions:
* There is no backward compatibility (i.e., a version 2 card cannot be used on version 1 machine).
* Upgrading the card to a more recent machine is permanent.
* When upgrading from one version to another, remaining plays will be carried over, and 50 plays will be credited to the card.
This feature was not present from Arcade Stage Zero to The Arcade however. Players with a save data on Arcade Stage Zero were rewarded with continued play benefits which included full tune tickets based on the number of cars owned that were fully tuned, up to 56 cars, titles based on the player's level, and avatar pieces, dressup tokens and avatar tokens based on the player's mileage.
Players with a save data from Sega World Driver Championship were rewarded with a full tune ticket and avatar pieces based on the driver level.
There are 13 games in the series; 10 for arcades and 3 for home consoles.

## Game modes
### Legend of the Streets

    In the main story mode, players race with opponents from the manga with their opponents increasing in difficulty during the progression of the game. In the English versions of the game, until the release of Arcade Stage 4, their names are derived from the Tokyopop manga.

### Time attack

    Players race in a timed game to rank highest against other players at their current machine or online. From Arcade Stage Ver.2/Special Stage to Arcade Stage 6 AA, players could change stages' weather conditions. This feature was removed from Arcade Stage 7 AAX to Arcade Stage 8 Infinity.

### Bunta Challenge

    First started in Arcade Stage Ver.2 to Arcade Stage Ver.3/Street Stage the player races against Bunta Fujiwara, the legendary street racer in the Initial D series. Each time Bunta is defeated, the player will gain a level, and difficulty increases. In Arcade Stage Ver.3, the player loses 1000 points upon defeat. Regardless, the end credits still roll if you win or lose to Bunta. Bunta's car differs across levels, levels 1-6: AE86 Trueno, levels 7-11: AE86 Trueno w/TRD 20-Valve 4AGE Racing Engine levels 12-15: GC8V Subaru Impreza WRX STi Version V. This model was discontinued and removed in Arcade Stage 4/Extreme Stage. However, Bunta appeared as a final boss in Akina. It later returned in Arcade Stage 7 AAX (Only in Legend mode after clearing Rebirth mode). And soon returned in Initial D The Arcade in an update during the 20th anniversary which can be unlocked at Street Racer Grade C9.

### Online Battle

    This was introduced in Arcade Stage 4/Extreme Stage, this mode allowed players to race against others located in the same continent.

### Racer's Event

    Introduced in Arcade Stage 5 to Arcade Stage 8 Infinity. Only two modes are included in-game, such as online battle and time attack.

### Tag Battle

    Introduced in Arcade Stage 6 AA through to Arcade Stage 8 Infinity, this mode allows players in the same location to team up. One player drives uphill and the other downhill to race with rivals. Matches are made based on past racing results, pitting drivers with similar levels against each other. When there is a difference in the level with your tag partner, the stronger driver will match with a stronger driver and a weaker driver with a weaker driver. The team with the highest score wins.

### Project Kanto's Fastest/Operation Kanto

    First introduced in Arcade Stage 7 AAX, this mode is similar to tag battle mode, where players race against the rival characters based in the manga from Gunma to Kanagawa area. In races against Project D's Ace, courses are random. In Arcade Stage 8 Infinity, new rivals include Tohru and Atsuro in Momiji Line, Sakamoto and Wataru in Sadamine Rain, and The Lan Evo Teams in Tsuchisaka.

### Theory of Streets

    Introduced in a content update for The Arcade, this mode allows the players to verse up to 2-3 other bots based on real players around the world on Sega's official servers. Players can choose their mentor to build their friendship with and earn rewards by beating the bots, and choose their opponents ranging from different street racer grades.

Released on 25 February 2009 in Japan, Initial D Arcade Stage 5 was the second game in the series released on the Sega Lindbergh hardware. A few notable differences include massive physics changes.

The character designs are taken from New Initial D the Movie with entirely new BGMs that are rock songs from the films such as Backdraft Smiths, Clutcho, The Hug Me, The Valves, and Gekkou Green. A small number of Eurobeat songs from previous games are also featured but have to be unlocked. Rain condition was removed as the New Initial D movies featured no race in such condition.
As like Stage 4 (which arcade system board has changed too), a number of vehicles and tracks are unavailable upon launch, but later added back through free updates later in the year.

### The Arcade

Released on the Sega ALLS MX2.1 arcade system and as upgrade kits for Initial D Arcade Stage Zero and Sega World Driver Championship on 25 February 2021, and later 29 July 2021 outside of Japan as an export version. The game had run a location test period on 23–24 July 2020 which allowed players to play the game in its beta phase. The location test gave out an Initial D The Arcade themed Aime card and an Initial D The Arcade tachometer in the style of Arcade Stage 8 Infinity for use in Initial D Arcade Stage Zero. The game is powered by Unreal Engine 4 instead of Sega's proprietary engine used for the previous titles. Unlike the previous arcade stage games, the story mode cutscenes are presented with a manga style filter with manga panels shown as the voice acting is absent aside from the countdown used in the story mode and when the cabinets are set to 2 player or 4 player vs mode. Certain character models like the ones used in the Theory of streets, associated with the cars and used on the game's season splash screen are reused from previous arcade stage titles. In 2023, Sega worked along with Wahlap to bring Initial D The Arcade to mainland China with full localisation.
Players who had a save file from Initial D Arcade Stage Zero or Sega World Driver Championship on their Aime card were given continued play benefits rewards which included avatar items from those games, avatar and dress-up tokens, full tune tickets depending on the number of full tuned cars the player had owned in Arcade Stage Zero or driver level in Sega World Driver Championship, and titles based on the player level in Arcade Stage Zero.
Like Arcade Stage Zero, the game launched with a small number of courses and cars with more to be added over the course of its live service. Certain collaboration events have made their return like MF Ghost, the Touhou Project featuring extra characters for the events and Hot Version. New collaboration events have occurred with Wangan Midnight, Lifeguard, Sega's Hatsune Miku's Project Diva, Chunithm New, Pop Team Epic, and Quintessential Quintuplets.
On 14 April 2022, a promotion was held for Sega's Initial D series 20th Anniversary. In an update, Bunta's Challenge was reintroduced. And play stamp cards distributed included keychains, start screen background, and tachometers that reminiscent the previous Arcade Stage titles, under neon, avatar pieces and background musics two of which were made by Dave Rodgers and one from Sega that debuted from Arcade Stage 6 AA. The three background music were brought back two times in the next two play stamp cards rerun.

### Special Stage

Initial D Special Stage was released on 26 June 2003, for the PlayStation 2 and was re-released on 26 February 2004, under the "PlayStation 2 the Best" label. Initial D Special Stage is based on Initial D Arcade Stage Ver.2 with additional Japanese voices for the first time and contains many features exclusive to this game. Initial D Special Stage is also the first home-console Initial D game published by Sega.
This version contains a story mode that allows the player to reenact racing scenes from the Initial D manga series (up to Vol. 25 at the time of publication), as well as several new courses then not seen in the arcade versions of the game. In one of these courses, Shomaru went on to appear in Initial D Arcade Stage Ver.3/Street Stage. Real Myogi was later added back in Initial D Arcade Stage 4/Extreme Stage. Momiji Line would not return until Initial D Arcade Stage 8 Infinity. Bunta's Challenge is noticeably absent in the game.

### Street Stage

Initial D Street Stage is a PSP-exclusive game based on Initial D Arcade Stage Ver.3. This game features Dogfight by M.o.v.e. as its intro theme, which also used as the first opening theme of Initial D Fourth Stage. The legend of the street mode, which pits players against the rival characters are the same as the arcade game, but Akina (Snow) is removed, meaning the battle with Miki is also removed, although his theme can be found in the game's BGM files.

## Reception

Initial D Arcade Stage (2001) sold 2,534 hardware units in Japan up until 2004. Initial D Arcade Stage Ver. 3 sold 673 units between April 2004 and March 2005. Combined, both versions of the game sold approximately 3,207 units up until March 2005. At a price of $2,130, the game grossed approximately $7 million in hardware sales up until March 2005.
Initial D Arcade Stage 4 sold 3,904 units in 2007, including 3,056 units by March 2007, and 848 during April–September 2007. At a price of $4,250, the game grossed approximately $17 million in hardware sales up until 2007.
In total, the Initial D Arcade Stage series has sold approximately 7,111 hardware units in Japan up until 2007, grossing approximately $24 million in hardware sales.
In 2014, Patrick Michael, Sega Amusements' head of local R&D, explained Initial D's lack of popularity in Europe: "Games like Initial D, which is a fantastic driving game but it's a one-on-one race where you're either in first place or last place. In Japan it's very popular, but in Europe no-one wants to be in last place, really - you want a much more open road, more AI cars and more of a feeling of achievement."
